Ixxxii NATURAL HISTORY. 



a dredge, near Felix Harbour. It was also taken at a short distance from the west 

 coast of Greenland, but seems to have entirely escaped the notice of Fabricius. We 

 have in former voyages found it abundantly in various other parts of the Arctic Seas, 

 but nowhere so numerously as near the Low Island (of Phipps), Spitzbergen, where it 

 was first discovered. It has recently been brought from the shores of Kamtschatka 

 and California, by Captain Beechey, as have also several hitherto undescribed species 

 of Crustacea, but of which no account, it is much to be regretted, has yet been 

 pubhshed.

Owing to the peculiar formation of the second pair of legs, in this singular animal, 

 it has become necessary to estabhsh a new genus, of which it is the only known spe- 

 cies ; and I have much pleasure in dedicating it to my friend, Captain Edward Sabine, 

 of the Royal Artillery, by whom it was discovered in the west coast of Davis's Straits, 

 during Sir Edward Parry's first voyage to those regions. His very accurate descrip- 

 tion is as follows : " Length four inches ; colour varied, red and white above, white 

 beneath ; thorax seven carinate, the three lateral carince on each side serrate, the 

 middle one with strong spines ; rostrum short, curving down between the eyes, grooved 

 in the centre ; the five upper carinae carried on in very faint rudiments along the back ; 

 the terminal setae of the superior antennae inserted nearly in the same horizontal line, 

 the interior one being the longest ; the first joint of the inferior antennae scarcely pro- 

 duced beyond the middle of the squama ; a strong spine in the abdomen directed for- 

 ward between the chelate legs; the last joint of the pediform palpi subacuminate.
